From this total are found in the Cerrado 251 species, including 32 endemic from this biome. This work aimed to establish an overview of the taxonomic composition, richness and abundance of the community ofmedium and large-sized mammals in the Cerrado area in the county of Arenopolis State of Goiás Brazil.It was done four (04) sampling campaigns from October - 2009 up to November - 2011, with eight (08) days of effective sampling per campaign, with the use ofthree (03) complementary methods which were, camera-traps, linear transects, diurnal and nocturnal with the use of Sealedbean.In this study were cataloged 23 species distributed in 09 (nine) orders and 16 families, with a total of 169 individuals registered, from which 13 species are in some lists of endangered animals. The species Hydrochoerushydrochaeris was the most frequent during the studies with 14.20% of the records and 24 individuals, followed by Nasuanasua with 11.24 % and 19 specimens, in the side of lower frequency Puma concolor and Puma yagouaroundi had this index reduced to 0.59% each, on the basis of the record of these ones have occurred only once. The richness found in the study area is still incomplete and the results must be more conclusive as new steps of faunal study are performed. The different methods used to obtain the records from medium to large mammals were complementary amongthemselves, which are considered to be of low evasionbased on the non-capture and stress of the animals. From the medium and large-sized mammals cataloged, part is in danger of extinction, even being considered of wide distribution in the Cerrado. However, the achievement of a directed faunal monitoring, mainly to these species, might benefit the mammal species found in the study area, assisting and directing efforts of handling these species. / Dentre a fauna brasileira os mamíferos representam cerca de 701espécies, dos quais 30% ou 210 espécies são consideradas endêmicas do Brasil. Desse total são encontradas no Cerrado 251 espécies, sendo 32 endêmicas. O presente trabalho teve como objetivo estabelecer uma visão geral da composição taxonômica, riqueza e abundância da comunidade de mamíferos de médio e grande porte em área de Cerrado, no município de Arenopólis,estado de Goiás. Foram realizadas quatro campanhas de amostragem, entre outubro de 2009 e novembro de 2011, com oito dias efetivos de amostragem por campanha, com a utilização de três metodologias complementares (armadilhas fotográficas, transectos lineares diurnos, e, noturnos). Foram catalogadas 23 espécies distribuídas em nove ordens e 16 famílias, com um total de 169 indivíduos registrados, dos quais 13 espécies estão em alguma lista de animais ameaçados de extinção. A espécie Hydrochoerushydrochaerisfoi a mais freqüente durante os estudos com 14,20% dos registros (24 indivíduos), seguida de Nasuanasua com 11,24% (19 espécimes), com menor freqüênciaPuma concolor e Puma yagouarounditiveram índice reduzido (0,59% cada), em função do registro destas terem ocorrido apenas uma única vez. Os diferentes métodos utilizados para a obtenção dos registros dos mamíferos de médio e grande porte foram complementares entre si.Dos mamíferos de médio e grande porte catalogados, parte encontra-se em perigo de extinção, apesar de sua ampla distribuição no Cerrado. Realçou se, porém, que a realização de monitoramento faunístico direcionado, principalmente a estas espécies, pode beneficiar a mastofauna encontrada na área de estudo, e assim, desencadear esforços corretos e adequados de manejo à conservação destas espécies.
